Sorry to intrude on this thread, but I noticed a few things.
The first being that the drive partitions are not set correctly. If I recall correctly, the partition types need to be set to "fd Linux raid auto"

Make sure the partitions are set to raid before attempting the mkraid function.

Thanks for the reply. Should I be using a different version/release that would work better for RAID? If so, pls let me know. As far as your info requests, see below. thanks. mike.

OK, so RAID support is in the kernel and you've got the required modules loaded. What about your IDE drive? IIRC, you arn't using one of the kernels with IDE built-in, and it doesn't look like you're loading any IDE modules based on the above.
Can you access the low-level /dev/hdX devices that make up your RAID?
What does "fdisk -l /dev/hdc" and "fdisk -l /dev/hdd" show?
Are you *REALLY* trying to build a RAID5 device with two partitions on the same drive (/dev/hdd1 & /dev/hdd2 in your example raidtab, which go along with /dev/hdc1)? If so, I'm not sure that will work, and it wouldn't be recommended in any case...
I wondered about the kernal in the uname -a, but when I d/l'd the kernal from your website, it was called, linux-2.2.19-3-LEAF-RAID-IDE.zImage.upx. Yet, my uname -a doesn't include IDE.
# fdisk -l /dev/hdc

As far as my raid5 device, I just want to make sure I can get the raid5 working before I buy a 3rd drive. My test set is 1 4gb drive (hdc) and an 8gb drive (hdb). I created 3 partitions each +3072M on the two devices and am trying to build the raid5 test. I also tried to do this with just doing raid1 on /dev/hdc1 and /dev/hdd1 and got the same error on the same command.
thanks. mike.
